A key question for HUDF astronomers is whether the universe appears to be the same at this very early time as it did when the cosmos was between 1 and 2 billion years old. The ACS uncovered galaxies that existed 800 Australia 3Dice No Deposit Bonus Code years after the big bang (at a redshift of 7). The NICMOS sees even farther than the ACS. The NICMOS reveals the farthest galaxies ever seen, because the expanding universe has stretched their light into the near-infrared portion of the spectrum. Where the HDFs showed galaxies when they were youngsters, the HUDF reveals them as toddlers, enmeshed in a period of rapid developmental changes," Stiavelli says. Both images reveal galaxies that are too faint to be seen by ground-based telescopes, or even in Hubble's previous faraway looks, called the gold flows Deep Fields (HDFs), taken in 1995 and 1998. Though ground-based telescopes have, ... Read more »
